It uses it's own USB 2.4 Ghz mini receiver. I'm booting multiple OS's on this computer. It works fine in Windows 10, was recognised instantly, no driver required. It works in Linux. It even works in the UEFI BIOS, which suggests it's a pretty standard HID device. It also works on my Macbook Pro in OSX. Windows 7 however, is another matter. I just get the "Device driver software was not successfully installed" message. No driver is available from Windows Update. No driver is available from Asus website and neither was one supplied in the box. The product is supposedly compatible with Windows XP onwards. Searching on the hardware ID leads to some sites that want you to install their driver application, but I'm wary of installing anything from a random internet site. I have tried - 1) Unplugging the device and using a different port 2) Uninstalling the 2.4G Receiver device in Device Manager and rebooting 3) Manually trying to install the 2.4G Receiver as a generic "USB Input Device" (driver installs but mouse still does not work) 4) Scanned for malware, viruses, etc. Installation is clean 5) Tried to get it working in Safe Mode. Doesn't work. There may be some clues to what is going on. Uninstalling the 2.4G Receiver device in Device Manager, and rebooting helps in as much as at the W7 login screen, the mouse works for a short while, but on logging in, after some activity, I get the driver error message and the mouse stops working again.. I would be very grateful if anyone could help out with this! Thanks I attach screenshots from Device Manager. Please let me know if any further information would help.
